Optimum grinding condition of Borazon CBN grinding wheel made clear through the ground surface integrity.

Munehiko Yokogawa, Kazuhiko Yokogawa

Abstract

An optimum grinding condition was found by making clear the relation among the grinding performance of CBN grinding wheel, the grinding mechanism and the ground surface integrity. Following results are obtained : (1) The ground surface integrity observed through grinding chips, ground surface state, residual stress, crystallinity, structure and hardness distribution take a turn for the worse in slipping area. (2) The degree of worse depends on the load rate put on cutting edges. (3) The condition which wheel life is the longest, i.e., (g/a)-2.29 l1.76 = 1.98 × 109 is an optimum grinding condition including the ground surface integrity.
